In order to easily navigate relevant or related pages, I like to create a block of ‘sibling entities’ that shows up at every entity display. For example, a Course entity has lessons, and on every lesson pages I want to show a list of ‘sibling’ lessons that all refer to the same course. This list needs to show up at every lesson display/page. How can I accomplish that?

You could create a formula field:

`Parent.Children`

where `Parent` and `Children` are the names of the relationship fields.

And if you want to exclude the item itself:

`Parent.Children.filter([Public Id] != [This Xxxx].[Public Id])`

`Xxxx` is the name of the database.

Is there a way to make this work for many to many relations?  
For example, some lessons are part of multiple courses.  
In a currently displayed lesson I want to display all sibling lessons of the courses that the currently displayed lesson is part of.

Use a lookup - Parents → Children
